Smile Help a DIY Female out!

Okay, So... this truck of mine isn't exactly the usual Honda's I deal with... but the man wanted it, so here I am...

I need help / advice! Like as of yesterday! - I have to get this fuel thing at least to something better then 9-12MPG!!!!
2003 Ram 1500 3.7L V6
Basic model, no power windows - nothing....
Only mod: has a slight lift kit -

It's what he wanted, what I bought, and what I'm gonna junk if I can't improve the gas mileage... any advice? Tuners I can buy? Chips? Fuel Pump? Details are a bonus, and A brand would be awesome too!

Thanks Ya'all!

Well, you did buy a full-size truck with an anemic V6 ... How many miles on the plugs? The throttle body may want cleaning. Is it throwing any codes?

Please detail what you have

etc, etc

Stock tires and wheels? what are they regardless, how worn? tire pressures run

details--details details... you get idea

Lot people here want to help but they REALLY got to know what they're dealing with----it matters!

Hate to sound like an *** but....the 3.7 is a dog.


Before KasperR34 comes in, sell it and buy a Hemi.

Welcome to DF.
For fücks sake I usually stick to telling the 4.7 guys to sell their "trucks" and buy a Hemi but god damn, scrap that thing and buy a Hemi. Or do a Hemi Swap.

The 3.7 in the Jeep Liberty is slow, I can only imagine how hilarious it is in a Ram.

As said before, we need more info

Definitely slight lift please.

Stock rims and tires? Changed the air filter? Change the plugs? Check tire air pressure? Reset the PCM? Quad cab or single?

And what type of mileage are we talking about.. City / Highway? And it this calculated or per the computer. If strickly on traffic watch, you might not have that much of an issue. If out on the road, then definately something's off.

210hp V6 + 4800lb (I am assuming it's a RC) full size truck = **** mileage

Details, detail... ode to the details! Thanks for the welcome peeps! I would totally sell it, but it's a work truck, and I'm getting my baby come Christmas, Soooo.. POS is staying.
Mileage: 130,282
Ram 1500, Automatic, Short bed, Regular cab (2-3 seater), 2 door.
Complete tune up done at 128,000 Miles, Platinum spark plus (auto zone), oil change.. oh... don't forget about the new radiator, and "works" (ie. fan clutch, pulley, belt) that I just replaced because of a snapped fan about 2,000 miles ago << Lucky Ducky I wasn't! >>
It's got a lift kit on it for the trailor that is hauled about 1x a month, but nothing major. Stock tires, Stock wheels.
Truck is getting about 7-9 MPG on the streets and 12 Hwy! If I missed anything I'll get back to you all!

Did the complete tune-up include fuel system cleaning? I would service the transmission and differential too if that has not been done. Probably needs to be checked out with a scanner too to see if it running rich. I think these were rated for something like 18 hwy so you are down quite a bit. With that age engine you might not be able to get 18 anymore but you should be able to do better than 12.

Only major issues I see are the platinum spark plugs and the lift/tires.

What SIZE tires are they? Stock should be either 245 or 265/70/17.

When the truck pulls up, i'm going to check out the tire size... they are just average tires... You see I was thinking of slapping a mod into this like a chip or something if they make them?
I can run it to pull up to see what they codes are tossing out tonight, lets see what it says.... He got the smaller engine to save a little on the gas mileage... his bad. Push come to shove- i'm trading in!

Don't waste your money on a $300+ tuner for a V6 Ram...... Not worth it.

You should be getting around 16-18 MPG average unless the previous owner did something stupid to it... or your man has a heavy foot....?

If there isn't a check engine light then I am more inclined to believe that there is a problem with the "driver mod".... lol

Fuel economy issues are nearly impossible to diagnose over the internet, but they usually have to do with the following:

- Bad Spark Plugs (Get rid of those Platinums they are hurting your truck, get Copper Plugs).
- Oxygen Sensor(s) Problem
- Catalytic Converter Problem (or is missing)
- Dirty Throttle Body
- Sub-Par Compression
- Oversized Tires Installed
- Heavy Foot (Driver Mod Needed... lol)
- Transmission Overdrive Problem (not going into over-drive)
- Too much weight in the truck (would take an additional 750#+ to cause that kinda drop not including driver)
- Climate (including Elevation, Terrain Type, Temperature, etc.)
- Lack of Back Pressure (usually caused by over sized aftermarket exhaust or exhaust leak)
- Bad MAP and/or IAT Sensor(s) - Causing incorrect air/fuel ratio mixture (aka running rich)

Those are the most common causes (not in any particular order), but it will be very difficult to diagnose over the web.

Wow---You guys really ROCK---GOOD JOB!

Sounds like everything is pretty well covered. I believe the platinum plugs would not cause that much of a drop, but get everything back to OEM condition to eliminate the possibilities first--and yes, the platinums should go, put the coppers in that came with it from the factory.
